Adjustable Pillow

ABSTRACT

An adjustable pillow includes a pillow cover having a plurality of removable pillow layer inserts. The pillow layer inserts can be of various thicknesses and firmnesses to permit adjustment for overall pillow height, overall firmness, and surface firmness upon insertion into the pillow cover. The total height of the pillow depends on the total height of the various inserts being used, the overall firmness depends on whether the inserts are soft, medium, or hard, and the surface firmness depends on the firmness of the topmost inside layer. To avoid movement of the inserts relative to each other while sleeping, at least one portion of each of the inserts is removably attachable to a corresponding portion of at least one other insert.

TECHNICAL FIELD

The present invention relates to the field of pillows, and in particularto pillows that can be adjusted through the use of inserts.

BACKGROUND ART

People have traditionally used pillows that come in many shapes, sizes,and styles. Pillows can be made with different heights and firmnesses tosuit the desires of the sleeper. Some people are more comfortable andsleep better using a pillow that is relatively soft, while others prefera pillow that is firmer. Similarly, some people prefer a relativelyhigh, tall pillow while others are more comfortable with a relativelyflat pillow. Some users might even want a pillow of a particular heightand firmness part of the time and of a different height or firmnessanother time. Thus, it would be advantageous for a pillow to beadjustable in firmness and height, and various attempts have been madeto provide such flexibility. Some people have a physical malady thatmakes an adjustable pillow desirable, such as an orthopedic ortherapeutic pillow.

Some pillows have segmented sections, each of a different firmness orsize. Adjustability is typically achieved by moving the pillow so thatthe appropriate section is directly under head, leaving the undesiredsections still attached but moved away from the head of the user.

Pillows can be quite expensive and therefore it would be advantageous ifconventional pillows that have lost their shape, size, or firmness couldbe restored without the expense of purchasing a replacement pillow.Unfortunately, conventional pillows without removable inserts can beadjusted or refreshed only by entirely replacing the pillow.

Although pillows have been made with replaceable inserts, providingadjustability, in actual use, the inserts have an unfortunate tendencyto move around or bunch up inside the surrounding pillow cover or pillowcase. Sleepers tend to move around while trying to go to sleep, whilethey are asleep, or while they are between cycles. They may push on orotherwise try to reshape their pillow to a more comfortable position,even while unaware of their action. This generally does not cause aproblem with a conventional pillow, but when there are multiple pillowinserts inside the pillow cover, the activity of the sleeper may causemovement of one insert relative to another, such as one insert bunchingup or shifting relative to another insert, resulting in the pillow nothaving the desired feel or characteristics that had been carefullyconfigured by the insertion of the multiple inserts. A way of preventingthat relative movement of the pillow inserts would be desirable.

From the discussion above, it should be apparent that there is a needfor an easily adjustable pillow cover that can be used with aconventional pillow and provides different firmness and thickness acrossthe entire sleeping area of the pillow. The present disclosure satisfiesthis need.

FIG. 1 illustrates pillow 100 according to one embodiment, in the formof a pillow comprising pillow cover 110. Pillow cover 110 is shown asbeing a cloth cover although a variety of other cover types arecontemplated with the cover providing confinement means relative to allcushion components encompassed by the cover as explained in greaterdetail below. Pillow cover 110 includes exterior layer 120 which, in apreferred embodiment, is a layer of material that provides, in a headpillow embodiment, a pleasant head contact feel (e.g., soft face contactmaterial) such as a high thread count cotton or silk fabric and is ofhigh strength and suitable thickness to withstand direct handlingcontact. Exterior layer 120 is shown extending fully across the top 130,the bottom 140 and along long intermediate side 150 of pillow 100.Typically, end 160 of the pillow cover 110 is sewn closed, while theother end 170 is closable using a zipper 180 or some other type ofclosure mechanism, such as buttons, snaps, hook and loop fasteners, etc.The closable end 170 can then be opened whenever an insert is to beadded or removed from the pillow 100. If desired, a pillow case (notshown in FIG. 1) can be placed around the pillow 100 for additionalcomfort of the sleeper or protection of the pillow 100. The term “pillowcover” is sometimes referred to in the industry as a pillow protector ora pillow sham.

Although as illustrated in FIG. 1, the pillow 100 and therefore pillowcover 110 are of a substantially rectangular shape, embodiments of theadjustable pillow 100 and pillow cover 110 can be of any desired shape,with the pillow cover 110 having a shape that substantially correspondsto the shape of the pillow 100. As illustrated in FIG. 1, the closableend 170 is one of the shorter ends of the rectangular pillow, theclosable end 170 can be any side of the pillow 100 and in someembodiments can extend across multiple sides of the pillow, giving alarger opening for insertion of pillow inserts. Some embodiments mayhave multiple closable openings, such as on both ends of the pillowcover. In other embodiments, the pillow cover may be formed in twoseparate sections that can be attached to each other after pillowinserts are placed in one of the two sections.

The pillow 100 as illustrated in FIG. 1 is of a common bed pillow shape,having a “height” defined as a vertical dimension of the pillow 100 whenviewed in cross section, perpendicular to a plane defined by the lengthand width of the pillow 100, when the pillow is not compressed by a heador other object resting on the pillow. The height of the pillow 100 mayvary as desired across the pillow 100. For example, a common bed pillowconfiguration has a variable pillow height with a maximum at the centerof the pillow and a minimum towards the ends of the pillow. However,embodiments may have a flat or constant height configuration if desired.

In some embodiments, pillow inserts may be provided with the pillow 100,allowing the purchaser to customize the pillow 100 to the desired heightor firmness. A set of three pillow inserts 200 is illustrated in FIG. 2,comprising inserts of different relative firmness and thickness. A firstinsert 210 is relatively soft and thin while a second insert 220 is ofmedium firmness and thickness, and a third insert 230 is relatively hardand relatively thick. These thicknesses and firmnesses are illustrativeand by way of example only. The firmness of the pillow inserts does notneed to correspond with the thickness as illustrated. Although threepillow inserts are illustrated in FIG. 2 for insertion into the pillow100, the number is illustrative and by way of example only, and adifferent number (including none) may be provided with the pillow 100.In addition, pillow inserts can be provided independently of the pillowcase 12. That is, pillow users can selectively mix and match thedifferent firmness and thickness of the pillow inserts as desired.Varieties of pillow inserts may be assembled, such as a group of allsoft pillow inserts, all pillow hard pillow inserts, or any combinationin between. In addition, the user may determine the overall height ofthe pillow by the thickness of the various pillow inserts which areselected. In this way, individual users can tailor the pillow 100 totheir own preference.

FIG. 3 is a sectional view that illustrates the pillow 300 with threepillow inserts 320, 330, and 340 placed in a pillow cover 310 to providean initial height, overall firmness, and surface firmness. For clarityof the drawing the closure mechanism of the pillow cover 310 is omittedfrom FIG. 3. The shape of the pillow inserts 320-340 is illustrative andby way of example only, and any shape pillow inserts may be used,including a more traditional pillow shape that is thicker at the middlethan at the ends. The total cross-sectional height of the adjustablepillow 300 as illustrated in FIG. 3 is substantially equal to thecombined height of any padding material in the pillow case 310, theheight of the first soft pillow insert 320, the height of the secondmedium pillow insert 330, and the height of the third firm pillow insert340. The overall firmness of the pillow cover 310 with pillow inserts320-340 is the firmness provided by the three pillow inserts and thepillow cover, as indicated by the resistance to “flattening” produced bythe combination. The surface firmness of the pillow cover 310 and pillowinserts 320-340 is the perceived firmness to the sleeper. Assuming thatthe pillow cover 310 has no padding material that would substantiallyalter the perceived firmness of the underlying top-most insert, then theperceived surface firmness would be the firmness of the pillow insertclosest to the sleeper's head. In FIG. 3. therefore, the initial surfacefirmness of the pillow 300 is determined by the firmness of the top-mostsoft pillow insert 320. The arrangement and ordering of the pillowinserts 320-340 is illustrative and by way of example only, and othernumbers and characteristics of pillow inserts may be used as desired.

As described above, a user can adjust the arrangement of the inserts320-340 to adjust overall pillow height, overall firmness, and surfacefirmness.

The total height of the adjustable pillow depends on the total height ofthe various pillow inserts being used. The pillow inserts may all beequally thick or they may vary in their thickness. If a collection ofpillow inserts have varying thicknesses, a greater number of possiblepillow thickness is achievable than with pillow inserts that are all ofthe same thickness. For example, if the medium pillow insert 330 of FIG.3 were removed, leaving only the soft pillow insert 320 and the firmpillow insert 340 inside the pillow cover 310, the overall height of thepillow 300 would correspondingly be adjusted, reducing the overallheight of the pillow 300. The greatest overall total height is achievedwith the greatest number of pillow inserts placed within the pillowcover 310.

Similarly, the surface firmness of pillow 300 may be adjusted bychanging the top-most pillow insert in the pillow cover 310 to a pillowinsert that is more or less firm than the previous top-most pillowinsert. Or if the pillow 300 is stuffed with inserts of differentfirmness, a sleeper may turn the pillow upside down so that thebottom-most pillow insert (pillow insert 340 in FIG. 3) becomes thetop-most insert, changing the surface firmness of the pillow 300 withoutchanging the configuration of the pillow inserts inside the pillow cover310.

It should be apparent that the softest perceived surface firmness isobtained if the soft pillow insert 320 is placed top-most, the firmestperceived surface firmness is obtained if the firm insert 340 is placedtop-most, and a medium perceived surface firmness is obtained if themedium insert 330 is placed top-most. The perceived overall firmness ofthe pillow 100 largely depends on the combination of pillow insertsplaced within the pillow cover 110. For example, if medium pillow insert330 of FIG. 2 were replaced with a second instance of firm pillow insert340, the overall firmness of the pillow 100 would increase; similarly,if pillow insert 330 or pillow insert 340 were replaced with a secondinstance of soft pillow insert 320, the overall firmness of the pillow100 would decrease.

The perceived overall firmness of the pillow 100 depends not only on thecombination of the different pillow insert firmnesses, but also to alesser extent on the surface firmness. That is, the perceived overallfirmness of the pillow 100 may change somewhat depending on the orderingof the inserts in the pillow cover 110. If the arrangement of pillowinserts 320-340 in FIG. 3 were reversed (or the pillow simply turnedover) so that the firm pillow insert 340 was topmost, not only theperceived surface firmness would increase, so would the perceivedoverall firmness. Accordingly, the perceived overall firmness of theFIG. 3 arrangement will be different from the perceived overall firmnessof the FIG. 3 arrangement is turned over, even though no change has beenmade to the pillow itself.

As explained above, the adjustable pillow 100 can be used in combinationwith a conventional pillow to provide adjustability that otherwise wouldbe lacking. Conventional pillows often become flat and lose their heightdue to the constant weight and pressure of the head upon the pillowsurface. Pillows are often thrown away due to wear and tear. By addingpillow inserts such as one or more of pillow inserts 200 to an oldpillow in a pillow cover 110 (where the old pillow becomes effectively apillow insert), the pillow can be restored to an original or preferredpillow height and firmness. Often the users of conventional pillowsbecome attached to the top surface to which they have become accustomed.Such users may add one or more pillow inserts 200 under their old pillowinside the pillow cover 110, thus improving overall height whileretaining a preferred or familiar top surface.

FIG. 4 is a top view of a corner 410 of a removable pillow insert 400that has been formed with a means for attaching the pillow insert 400 toother pillow inserts. An opening 420 is formed through the corner 410.In some embodiments, the opening 420 may be simply an opening cutthrough an upper and a lower surface of a casing 430 of the pillowinsert 400 which holds the feathers, down, foam, or other pillowstuffing material that provide firmness or support for the pillowinsert. If the edges of the opening 420 are unclosed, providing a pathfrom inside the pillow insert cover to outside, stuffing material mayescape from the pillow material through the opening 420, which would beundesirable. Therefore, in some embodiments the area around the opening420 may be sealed off from the rest of the pillow insert 400 across aline 440, to prevent the stuffing material from reaching and possiblymigrating through the opening 420 from the inside of the pillow insertcover 410 to the outside of the pillow insert cover 410. The line 440may be formed by single or double stitching across the pillow insertcasing 430. The position, shape, and orientation of the line 440 is notsignificant, and the line 440 may be placed and formed in any way thatprevents stuffing material from reaching the opening 420. Alternately,in some embodiments the perimeter of the opening 420 may be sewn,binding the top and bottom surfaces of the pillow insert casing 430together, preventing the stuffing material from escaping through theopening 420. For example, a stitching technique may be used similar tothat used in making button holes in a garment, as long as the buttonhole stitching stitches the top and bottom surfaces togethersufficiently to prevent stuffing material from being able to passthrough the opening 420. If the stuffing material is large enough thatit cannot pass through the opening 430, the line 440 and any closuretechnique around the opening 430 may be omitted if desired.

Any desired size opening 420 may be used. The size may be chosen basedon the technique selected for using the opening 420 for binding thepillow cover 400 to another pillow cover. Although illustrated as anelliptical opening in FIG. 4, any desired shape may be used to form theopening 420. Although described as an opening, when not under pressurefrom the contents of the pillow insert 400, the opening 420 may appearessentially closed, without any large space between the sides of theopening. For example, a simple straight cut through the top and bottomsurface of the pillow insert casing 430 may be used. As illustrated inFIG. 4, the opening 420 is oriented substantially at a 45° anglerelative to a 90° formed by the corner 410, however, the corner 410 maybe formed at any desired angle and the opening 420 may be formed at anyangle or position relative to the corner 410.

Although the opening 420 is illustrated in FIG. 4 as formed in thecorner 420, in some embodiments, the opening 420 may be formed at otherpositions along an edge of the pillow insert casing 430. Alternately,some embodiments may employ a tab or other similar object that is sewnor otherwise attached to an edge of the pillow insert casing 430, wherethe opening 420 is formed in the tab.

FIG. 5 is a plan view of three embodiments of fasteners that may be usedwith the opening 420 to attach two or more pillow inserts 400 together,configured for insertion through the opening 420. The fasteners 500,520, and 540 function similar to cufflinks that are used to close Frenchcuffs on a shirt together. One end of fastener 500, 520, and 540 ispushed through the openings 420 in two or more pillow covers 400. Whenin place, the fasteners 500, 520, and 540 hold the pillow covers 400 inplace relative to each other, preventing any of them from significantrelative movement, thus preserving the desired and configured feel ofthe pillow 100 that might otherwise be degraded by the relative movementof the pillow inserts 400.

Fastener 500 illustrates a simple fastener that comprises two roughlyspherical end elements 505A and 505B, held together by link 510. Thefastener may be manufactured of any desired material, such as metal,plastic, thread, or fabric. In one example, fastener 500 may be made ofsilk thread formed as a small rope which is knotted on both ends to formthe end elements 505A and 505B and link 510. Although illustrated inFIG. 5 as roughly spherical, end elements 505A and 505B can have anydesired shape that is sufficiently small to be able to fit throughopenings 420 of the pillow inserts 400, but sufficiently large that thefastener 500 is not easily dislodged from the openings 420 once insertedthrough them.

Fastener 520 is a mechanical cufflink type of fastener, in which fixedend element 525 is attached to one end of a pair of links 530, while theother end holds a rotatable end element 535 that can rotate relative tothe pair of links 530. As with a shirt cufflink, rotating the rotatableend element 535 to be parallel to the pair or links 530 allows therotatable end element 535 to pass through openings 420 easily, then berotated perpendicular to pair of links 530. In the rotated position(illustrated in FIG. 5), the rotatable end element prevents dislodgingthe fastener 520 from the plurality of pillow covers 400.

Fastener 540 is a fixed fastener illustrating that the end elements 545and 555, which are connected by link 550, do not need to have the sameshape. As illustrated in FIG. 5, end element 545 is roughly spherical,while end element 555 is planar. In such a configuration, spherical endelement 545 is usually more convenient for pushing through openings 420.

Although links 510, 530, and 540 are illustrated as solid elements,embodiments may use forms such as small chains for the links, allowingmovement of the two ends of the fasteners 500, 520, and 540 relative toeach other. Preferably, the fasteners are small enough that should thesleeper's head happen to rest upon the portion of the pillow covers 400that are held together by the fasteners 500, 520, or 540, the fasteners500, 520, or 540 do not cause discomfort. The links 510, 530, and 540can be of any desired length, but preferably are long enough to allowattaching as many pillow covers 400 as the sleeper may desire to use atany given time.

The fasteners 510, 530, and 540 illustrated in FIG. 5 are illustrativeand by way of example only, and any other fastener configuration can beused that holds together pillow covers 400 when inserted throughopenings 420. Although only a single corner is illustrated in FIG. 4 ashaving the openings 420, embodiments may have openings 420 on two ormore corners or other attachment points as desired. This may allowattaching anywhere from one to all four corners of a set of rectangularpillow inserts 400.

By making the fasteners 500, 530, and 540 removable, a sleeper maydetach the pillow covers 400 from each other at any time the sleeperwishes to change the pillow configuration, such as by replacing onepillow insert 400 with another of different configuration, or to allowlaundering or repair of one or more of the pillow inserts 400.

Other techniques may be used for attaching pillow inserts 400 to eachother. For example, in FIG. 6, a button 610 may be attached to pillowcover 400, allowing the button to be used to connect the pillow insert400 to one or more other pillow inserts 400 by pushing the button 610through the openings 420 on the other pillow insert covers 400. In thisembodiment, each pillow insert cover 410 may have both an opening 420and a button 610, or in some embodiments, the pillow insert may haveonly the button 610, without the opening 420.

FIG. 7 illustrates a technique using snap fasteners according to oneembodiment. In this embodiment, a male snap fastener component 710 isaffixed to a first surface 720A of the pillow insert 400, while a femalesnap fastener component 720 is affixed to a second opposite surface 720Bof the pillow insert 400. The male snap fastener component 710 of afirst pillow insert 400 may then be snapped together to engage with thefemale snap fastener component 720 of a second pillow insert 400 toattach the two pillow inserts 400 together.

Another embodiment is illustrated in FIG. 8, in which a hook-and-loopfastener tape, such as VELCRO® tape, is applied to surfaces 830A and830B of the pillow insert 400. (VELCRO is a registered trademark ofVelcro BVBA.) The hook portion 810 is affixed to surface 830A and theloop portion 820 is affixed to opposite surface 830B, allowing hook orloop portion affixed to a corresponding surface of other pillow inserts400 to engage with and removably be attached to one of the hook or loopportions 810, 820 to attach the pillow inserts 400 together. The size,position, and orientation of the hook-and-loop fastener tape 810, 820 isillustrative and by way of example only, and any size, position, andorientation may be used as desired.

The fastening techniques illustrated in FIGS. 4-8 are themselvesillustrative and by way of example only, and any desired removableattachment technique may be used to attach and detach pillow inserts 400from each other, including zippers, magnets, and clips.

The above describes an easily adjustable pillow that providesconfigurability for different surface firmnesses, overall firmnesses,and height across the entire sleeping area of the pillow cover and alsois compatible with conventional pillows to provide them withadjustability. In addition, the pillow inserts may be attached to eachother to prevent relative movement of the pillow inserts as the sleeperuses the pillow, which would otherwise result in undesirable bunching orrolling of pillow inserts and diminish the perceived comfort of thepillow to the sleeper. Because the attachments are detachable, theadvantages of being able to swap out pillow inserts as desired isretained, without the disadvantages of having the pillow inserts modifytheir configuration and position.

Although disclosed above in terms of pillows, pillow inserts, and pillowcovers, the same techniques may be used on other types of bedding. Forexample a comforter may be inserted into a duvet cover and attached tothe duvet cover using any of the techniques disclosed above, fasteningthe comforter to the duvet cover to keep the comforter from shiftinginside the duvet cover, such as by putting a button on a corner of thecomforter and a button hole on the duvet cover, allowing the comforterto be attached to the duvet cover. Similarly, a pillow or pillow insertmay be fastened to a pillow cover to keep the pillow or pillow insertfrom shifting inside the pillow cover.
